30、o an IP network and also provides element management functions and control of the address resolution and resource management functionality satellite payload: part of the satellite that provides air interface functions NOTE: The satellite payload operates as a packet switch that provides direct unica
31、st and multicast communication between STs at the link layer. Satellite Terminal (ST): terminal that is installed in the user premises terrestrial host: entity on which application level programs are running NOTE: It may be connected directly to the Satellite Terminal or through one or more networks

MAINTENANCE: The ST port goes into this state o
34、n direct command from the NOCC. In this state it can still do connection setup/teardown, routing etc, but is prohibited from advertising these services to the local networks or to other STs. This state is to be used for diagnostic purposes only. OUT-OF-SERVICE: An ST port goes into out-of-service st
35、ate when the ST overall goes out of the active state or into one of the inactive substates of the active state or due to failure/deconfiguration of the port itself. In this state, the ST does not provide any services to either a local user or a remote ST. 4.3.2.2 Port level services Packet transit:
36、The service of delivering packets over the RSM-A system to other networks with/without QoS guarantees. Routing: The service of identifying routes available over the RSM-A system and advertising them locally. Interaction with terrestrial routing protocols to allow seamless IP routing over the RSM-A s
37、ystem. Connection setup: The service of setting up pre-scheduled/on-demand connections providing “virtual circuit-like“ channels over the RSM-A system by negotiating with the network. Multicast group setup: The service of setting up multicast groups for efficient point to multipoint communication ov

ETSI ETSI TS 102 189-1 V1.1.2 (2004-07) 154.4 ST protocol architecture 4.4.1 Data plane architecture The RSM-A network architecture provides a split between Satellite dependent functions and Satellite independent functions. The purpose of this split is as follows: separate the s
39、atellite specific aspects (i.e. a Ka-band GEO satellite with a packet switch) from the satellite independent higher layer. This separation is designed to permit future market developments, in particular IP enhancements; provide flexibility for the addition of more complex market segment-based soluti
40、ons (e.g. PEPs and Application Gateways). With some exceptions, functions in a satellite terminal can be conceptually categorized as link-specific and link-non-specific. RSM-A provides an interface to its transport core that is common for all network services, applications, and market segments. This
41、 interface is termed the Satellite Independent-Service Access Point (SI-SAP). In the OSI layering model, the SI-SAP is positioned between the link and network layers. With the SI-SAP so positioned, elements above the SI-SAP can, and indeed should, be designed without specific knowledge of the suppor
42、ting link layer. Hence the introduction of the SI-SAP into the system design affords the following benefits: Elements above the SI-SAP can be ported with greater ease to new satellite systems. Extensibility to support new higher-layer functionalities without major re-engineering of existing designs.
43、 This clause describes the user data transmission plane in the RSM-A ST. The functions of the various layers and the various SAPs are described below. The architecture for the baseline ST configurations is shown in figure 4.4. The RSM-A Core Layers consist of the SLC, MAC and PHY layers. The IP Adap
44、tation layers include the IP Plus Layer and the Transport Layer Performance Enhancing Proxies (PEP).

46、 architecture 4.4.2 CoS and related concepts Quality of Service (QoS) is the abstract notion of how well a particular sort of traffic is carried to its destination, relative to the needs of that traffic. Because, in general, different kinds of traffic have different QoS requirements, traffic is cate
47、gorized into different Classes of Service (singular: CoS). Traffic of a given CoS may be carried in different ways with the goal of providing the appropriate QoS for such traffic. ETSI ETSI TS 102 189-1 V1.1.2 (2004-07) 16In RSM-A the CoSes are directly supported by User Data Transport Services (sin
48、gular: UDTS), which are general characterizations of how traffic is queued and sent. The specific method by which a RSM-A packet is sent is termed a Packet Delivery Service (PDS). The PDS selected for transmitting a packet is related to the UDTS of the associated data traffic, but not in a strictly
49、one-to-one fashion. STs may operate in High Volume UpLink (HVUL) or Bandwidth-on-Demand (BoD) mode. Both modes of operation are described in BSM RSM-A SMAC/SLC Layer Specification TS 102 189-2 3. The association of these concepts is shown in figure 4.5 for BoD. The complete set of rules for mapping UDTS to PDS are given in BSM RSM-A SMAC/SLC Layer Specification TS 102 189-2 3.
